Maths challenge

I have a recipe for cheese scones, but I need to convert the units to grams and millilitres as that's all my scales and measuring jug show. The problem is my measurements are in fluid ounces (fl oz) and ounces (oz).

Can you use these conversion formulas to calculate the correct measurements?

1 ounce = (approx.) 28.35g

1 fluid ounce = (approx.) 28.413ml

Here's the recipe:

  • self-raising flour 8.5oz
  • butter 2oz
  • cheese 1.5oz
  • milk 5.5oz
